BACKGROUND OF DISCLOSURE Field of Disclosure

The present disclosure relates to a field of display technology, in particular to an array substrate and a display panel.

Description of Prior Art

At present, in an array substrate of a thin film transistor liquid crystal display (TFT LCD), an electric field of a data line may cause surrounding liquid crystals to flip, resulting in light leakage. Moreover, a distance between the data line and a pixel electrode is relatively short, thus a capacitive coupling of the data line to the pixel electrode may cause adverse effects such as crosstalk.

At present, in addition to providing a black matrix (BM) above the data line for light shielding, a data line BM less (DBS) technique may be used to remove the black matrix above the data line, and a DBS electrode may be provided above the data line, so that a potential of the DBS electrode is same as a potential of a common electrode on a color film substrate, so that corresponding liquid crystal molecules above the data line remain in an undeflected state at all times, thereby performing light shielding.

As shown in FIGS. 1 and 2 , a common electrode line 200′ (A com) may be used on a side of a data line 100′ to shield a lateral electric field of the data line 100′, so as to reduce an influence of the data line to a pixel electrode. However, using the common electrode line 200′ to shield the lateral electric field of the date line 100′ will reduce an aperture ratio of a pixel unit. Further, a sharing electrode line 300′ (share bar) of a sharing thin film transistor penetrates a main pixel region and a sub-pixel region vertically, thereby reducing a light transmission area of the pixel unit and reducing the aperture ratio and a transmittance of the pixel unit.

Embodiment 1

This embodiment provides a display panel. The display panel comprises an array substrate 100, a color film substrate disposed corresponding to the array substrate 100, and a liquid crystal layer disposed between the array substrate 100 and the color film substrate.

As shown in FIG. 3 , the array substrate 100 comprises a substrate 101 and a plurality of pixel units 102 arranged on the substrate 101 in array.

The substrate 101 is made of one or more of glass, polyimide, polycarbonate, polyethylene terephthalate, and polyethylene naphthalate. Therefore, the substrate 101 has better impact resistance and can effectively protect the display panel.

As shown in FIG. 4 , each of the pixel units 102 is divided into a main pixel region 1021 and a sub-pixel region 1022. Each of the pixel units 102 comprises a data line 1, a scan line 2, a first sharing line 3, a second sharing line 4, a first common line 5, a main pixel electrode 6, a sub-pixel electrode 7, a main pixel thin film transistor 8, a sub-pixel thin film transistor 9, a sharing thin film transistor 10, and a third sharing line 11.

As shown in FIGS. 3, 4, and 5 , the data line 1 is disposed on the substrate 101. In this embodiment, a material of the data line 1 is metal. In other embodiments, materials of the data line 1 may also be other conductive materials. For example, alloys, nitrides of metallic materials, oxides of metallic materials, nitrogen oxides of metallic materials, stacked layers of metallic materials and other conductive materials, or other suitable materials.

As shown in FIGS. 3 and 4 , the scan line 2 is disposed between the main pixel region 1021 and the sub-pixel region 1022, and intersects with the data line 1. That is, an extension direction of the data line 1 is not parallel to an extension direction of the scan line 2. In this embodiment, the extension direction of the data line 1 and the extension direction of the scan line 2 are perpendicular to each other. In this embodiment, a material of the scan line 2 is metal. In other embodiments, materials of the scan line 2 may also be other conductive materials. For example, alloys, nitrides of metallic materials, oxides of metallic materials, nitrogen oxides of metallic materials, stacked layers of metallic materials and other conductive materials, or other suitable materials.

As shown in FIGS. 3, 4 and 5 , the first sharing line 3 is disposed between the substrate 101 and the data line 1, and parallel to the data line 1. In this embodiment, a material of the first sharing line 3 is metal. In other embodiments, materials of the first sharing line 3 may also be other conductive materials. For example, alloys, nitrides of metallic materials, oxides of metallic materials, nitrogen oxides of metallic materials, stacked layers of metallic materials and other conductive materials, or other suitable materials.

An electric field of the data line 1 is shielded by the first sharing line 3, and a coupling effect between the data line 1 and the first common line 5 is relieved by the first sharing line 3, thereby reducing crosstalk to the data line 1 by fluctuation of the first common line 5. A problem in the prior art, of using a common electrode line to shield a lateral electric field of a data line, resulting in a low aperture ratio of the display panel, is prevented.

As shown in FIGS. 3, 4 and 5 , the first sharing line 3 has a first central axis 12 parallel to the data line 1, and the first central axis 12 is a symmetrical axis. The data line 1 has a second central axis 13 parallel to the first sharing line 3, and the second central axis 13 is a symmetrical axis. The first central axis 12 and the second central axis 13 coincide with each other. The first central axis 12 of the first sharing line 3 coincides with the second central axis 13 of the data line 1 to prevent a situation in the prior art that the first sharing line 3 penetrates the main pixel region 1021 and the sub-pixel region 1022 vertically, thereby increasing an aperture ratio and transmittance of the array substrate 100.

As shown in FIG. 7 , one end of the first sharing line 3 is electrically connected to the second sharing line 4, and another end extends along the first axis 1011 from the sub-pixel region 1022 of one of the pixel units 102 to the main pixel region 1021 of an adjacent pixel unit 102.

Specifically, a difference value between the width of the first sharing line 3 and the width of the data line 1 ranges from 0 μm to 15 μm. When the difference value between the width of the first sharing line 3 and the width of the data line 1 is relatively small, an effect of shielding the electric field of the data line 1 by the first sharing line 3 is poor. When the difference value between the width of the first sharing line 3 and the width of the data line 1 is greater than 15 μm, the first sharing line 3 will occupy an aperture area of the array substrate 100, and the aperture ratio and transmittance of the array substrate 100 is reduced.

As shown in FIG. 5 , an insulating layer 14 is also disposed between the first sharing line 3 and the data line 1. The insulating layer 14 is mainly used to prevent contact between the first sharing line 3 and the data line 1 from causing a short circuit phenomenon. Materials of the insulating layer 14 may be one or more of SiO₂ and SiN_(x).

As shown in FIGS. 3 and 4 , the second sharing line 4 parallels to the scan line 2 and disposed between the scan line 2 and the sub-pixel region 1022, and spacedly disposed from the scan line 2. In this embodiment, a material of the second sharing line 4 is metal. In other embodiments, materials of the second sharing line 4 may also be other conductive materials. For example, alloys, nitrides of metallic materials, oxides of metallic materials, nitrogen oxides of metallic materials, stacked layers of metallic materials and other conductive materials, or other suitable materials.

As shown in FIGS. 3 and 4 , the first common line 5 parallels to the scan line 2 and disposed between the scan line 2 and the main pixel region 1021, and spacedly disposed from the scan line 2. In this embodiment, a material of the first common line 5 is metal. In other embodiments, materials of the first common line 5 may also be other conductive materials. For example, alloys, nitrides of metallic materials, oxides of metallic materials, nitrogen oxides of metallic materials, stacked layers of metallic materials and other conductive materials, or other suitable materials.

Wherein, the scan line 2, the second sharing line 4, the first common line 5, and the first sharing line 3 are disposed in a same layer. In this embodiment, the scan line 2, the second sharing line 4, the first common line 5, and the first sharing line 3 are made of a same material, so that the scan line 2, the second sharing line 4, the first common line 5, and the first sharing line 3 can be simultaneously prepared in one step, thereby saving processes and production costs.

Therefore, an additional occupation of the transmission area of the array substrate 100 is prevented, and the aperture ratio of the array substrate 100 is increased.

Embodiment 2

As shown in FIGS. 8 and 9 , Embodiment 2 includes most technical features of Embodiment 1. Embodiment 2 differs from Embodiment 1 in that the third sharing line 11 of Embodiment 1 is removed from Embodiment 2, and a second common line 15 is disposed at a position of the third sharing line 11 of Embodiment 1.

The electric field of the data line 1 is shielded by the first sharing line 3, and a coupling effect between the data line 1 and the first common line 5 is relieved by the first sharing line 3, thereby reducing crosstalk caused to the data line 1 by fluctuation of the first common line 5. The first central axis 12 of the first sharing line 3 coincides with the second central axis 13 of the data line 1 to prevent a situation in the prior art that the first sharing line 3 penetrates the main pixel region 1021 and the sub-pixel region 1022 vertically, thereby increasing the aperture ratio and the transmittance of the array substrate 100.
